Chicago is a very large city with two separately run and separately priced public transit systems serving the city itself and the extensive suburbs.
Different routes run at different times of the day, and an online search for the most up-to-date information for your specific travel times is HIGHLY ADVISABLE.
Many folks use the Chicago public transit options for business and pleasure, and they are designed for high capacity work commute times on weekdays and less frequent pleasure travel on weekends.
Public Transport from Chicago Airports:
There are three public transportation systems:
- Metra (light rail, trains to many places including other states)
- Chicago Transit Authority – CTA (buses and trains)
- PACE (buses)
